Paper describes how a single launch Mars Sample Return (MSR) mission could potentially be enabled by using of Electric Propulsion with Hall Thrusters: a well established, off-the-shelf technology commonly used on communications satellites today.
With so many opportunities in the Solar System it may be hard to choose destinations. Titan has a one quality that sets it apart: it is uniquely suitable for humans. One reason for robotic Mars exploration is that humans will arrive in due course. An identical justification applies to exploring T

Near Earth objects (NEOs) are attractive targets for spacecraft missions with the purpose of obtaining greater insight to the nature of the original bodies from which the terrestrial planets formed, without having to visit the Main Belt itself. Greater knowledge of NEOs directly sheds light on the origin and evolution of the asteroid belt, the formation of planets, and the history of the solar system. This report describes a search for NEOs that would be accessible for missions launching in...

(Taken directly from Jupiter Europa Orbiter Mission Study 2008: Final Report [1], Section 1.) Some 400 years ago, discovery of the four large moons of Jupiter by Galileo Galilei changed our view of the universe forever. Today Jupiter is the archetype for the giant planets of our solar system, and for the numerous giant planets now known to orbit other stars, and Jupiter's diverse Galilean satellites -- three of which are believed to harbor internal oceans -- are central to understanding the...
